Community Paramedics Addressing the Evolving Opioid Crisis: A Case Series Addressing the Kratom Derivatives 7-Hydroxymitragynine and MGM-15
Prehospital Emergency Care · 2026-10-22 · Added 25 October 2026
A US case series describes community paramedics treating severe withdrawal from concentrated kratom derivatives (7-hydroxymitragynine and MGM-15) with full-dose buprenorphine and rapid linkage to outpatient medication for opioid use disorder, with both patients retained in treatment at 30 days.
- Study type
- Case series
- Design
- Case series, US community paramedic buprenorphine program
- Participants
- 2 patients
- Main finding
- Buprenorphine 24 mg and 32 mg/8 mg with naloxone treated severe 7-OH/MGM-15 withdrawal; both patients were linked to outpatient treatment within 48 hours and retained in treatment at 30 days
- Caveat
- Two cases, no comparison or systematic outcome measurement
- Bottom line
- Context only
Why it matters in Australia (Medium relevance). Buprenorphine is not something Australian ambulances carry — adoption would need a guideline change — but concentrated 7-OH products are sold over the counter and online, and crews will meet the dependence and withdrawal they cause.
Learning goal
Recognise emerging synthetic kratom derivative toxicity and withdrawal presentations that may require buprenorphine-based management.

Ice-water immersion wins for drug hyperthermia
A systematic review of 71 studies (1,932 patients) comparing cooling methods for drug-induced (and exercise-induced) hyperthermia found ice-water and cold-water immersion fastest at ~0.16–0.17 °C/min and clearly superior to passive cooling.
